Acqua Marcia

The Acqua Marcia was an aqueduct in Rome, Italy, built during the Roman Republic.

History
This impressive system was the longest of the 11 Roman aqueducts, running a staggering 91 miles. Built between 144-140 BC, the aqueduct was named for its creator, praetor Quintus Marcius Rex. It was maintained and even expanded for the better part of 200 years, but, typical of any public service, by Nero's reign so many people siphoned water out of its for personal use the flow was barely a trickle by the time it arrived in the city.
